Give yourself a high five

List five things for which you are thankful.

As easy as 1-2-3, this is an exercise that delivers countless rewards.
Take it from Robert Emmons, a world-leading scientific expert on gratitude. By studying more than 1,000 people ages eight to 80, he and researchers linked the benefits of gratitude practice to stronger immune systems, a higher level of positive emotions, better sleep and more get up and go. Set aside time each day to reflect—perhaps first thing in the morning or last thing at night. You will thank yourself later!
